Three four hairy species are quite confusing and we have to follow the following keys from Flora of Peninsular India as below:

36 Leaves elliptic lanceolate or oblong, more than twice as long as broad

38 Stipules prominent ovate lanceolate or lanceolate

39 Stem with spreading hairs

41 Pods slightly exserted, 15-20 seeded …. C.hirta

41 Pods much exserted , 20-35 seeds

42 Leaves villous beneath; bracts often 3 lobed; pods subsessile ….. C.mysorensis

42 Leaves appressed pubescent beneath; bracts simple; pods shortly stalked …. C.ferruginea

38 Stipules minute or 0.

43 Pods as long as or shorter than calyx

44 Calyx to 0.8 cm long; upper two lobes connate except at tip; pods globose … C.linifolia

44 Calyx to 2.5 cm long; lobes connate at base only; pods oblong …. C. calycina
.

Erect branched herbs, silky pubescent. Leaves to 5.5 x 1.5 cm, oblong, obovate, apex obtuse, apiculate, base cuneate, pubescent; petiole 1 mm, stipule 0.5 cm, lanceolate, ciliate. Racemes lax, 6-8 flowered; flowers yellow, pedicels 0.5 cm; sepals connate at the base, 1.5 cm, lanceolate, tomentose; keel sepal linear; standard petal 17 x 8 mm, orbicular; wings 10 x 5 mm, oblong, obtuse; keel united, 1.5 cm long, enclosing the stamens and pistil; anthers dimorphic, larger 3 mm, smaller 0.3 mm; ovary 4 mm, oblong, style constricted at the bent, 1.3 cm long, puberulus, stigma oblique. Pod 3 x 1 cm, oblong, glabrous, shining; seeds many.

Flowering and fruiting: December-February

Crotalaria prostrata Rottler ex Willd. ??

Looks different from Crotalaria prostrata Willd.

Keys in Flora of Bhutan at Crotalaria‎ lead me to (15. C. ferruginea Bentham), 16 (16. C. humifusa Bentham) & 17 (17. C. acicularis Bentham)

I am ignoring the following on further checking these at

Crotalaria humifusa Benth. as per details herein &

Crotalaria acicularis at FOC illustration, POWO Florida plants YDHVN

I think it is close to Crotalaria ferruginea as per GBIF High resolution specimen BGO YDHVN

Thank you …! Crotalaria ferruginea Graham ex Benth.

I also think so. Pl. check comparative images in efi site.

Its Crotalaria L.

Yes it is already mentioned in the caption that it is Crotalaria but which one?

Could not find a match at comparative images at ‎Crotalaria

Does look like Crotalaria alata to me

http://frps.iplant.cn/frps/Crotalaria%20alata

Has this ID not been considered?

Crotalaria alata has flat, rather winged stem, isn’t it ?

I tried again, but could not find match as per comparative images at Crotalaria

Please have a look at Crotalaria triquetra. It looks close.

I am not sure … if it matchs !

Looks different from images at Crotalaria triquetra
Also does not have any distribution as per ILDIS

It is late evening, I collected during my posting at Sikkim and it is C. ferruginea, immediate response and am confident, please do match and intimate.

Yes, appears to match as per GBIF specimens from India- one and two.
